romero-sentence TABLE.

Application filed November 23,` 1926.V Serial No. 150,261.

The `present invention relatesto a inachine especially designed for gradingiand"v saclring vegetables and fruits, the primary object of the invention `being toprovide a device of this character wherein the grading and sackingmay be accomplished simultaneously, and lWith facility.

Another object ofthe invention is to provide a machine including an endless con- 1o veyor on which the vegetables or yfruit to be graded are positioned, the endless conveyor acting to carry the vegetables or fruit towards the discharge endl of the machine Where they are delivered into sacks.

A still further object of the invention is to provide lateral partitioning members above the conveyor, the latter partitioning members providingpassageivays for dcliv ering the articles being graded, laterally of the machine, novel means being provided at the ends of the passageivays for supporting sacks to receive the articles. i

W ith the foregoing and other objects in vieW which will appear as the description proceeds, the inventioiiresides in the coinbination andy arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the `precise embodiment of theinvention herein disclosed, may be made Within the scope of what is claimed, Without departing from the spirit of the invention.

Y Referring to the drawings: f

VFigure Al is a side elevational vieiv of a with the invention. i

Figure 2 is a plan view ofthe machine. Figure 3 is an end elevational view ol1A the machine. Y

Figure 4l is a fragmeiital view illustrating the conveyor construction.

Figure 5 is a side elevational view of the conveyor.

Figure 6 is a fragmental'view illustrat1 ing the means for adjusting the conveyor.

Referring to the drawings in detail, the device includes a frame embodying a table 5 supported by means of the legs 6.

The table embodies side boards Which have their forward ends extended downwardly as at 7 so that the vegetables or fruit may be readily and easily position-ed on the endless conveyor to be hereinafter more fully described.

. be rotated.

grading machine constructed in accordance Supported by the side boards of the iframe are rollers 8 disposed in spaced rela@ tionvvith each other, said rollersbeingde signed t'o support the endless conveyor 9 which endless lconveyor is constructed of aiplurality ofy rods 10 having substantially right angled ends 11 formed with eyes l2, the eyes of one vrod accommodatingV the ad- ]acent rod `to connect the adjacent rods.'

At one end Vof the frame is a shaft .13 which is provided with a-crank handle 14 at oneend thereof, whereby the Vsha-ft may Mounted on the shaft 13 are sprocketsV l5 over which the endless conveyor operates, the same being shown as engaging the sprockets. f Y

Atthe opposite end of the'inachine is a shaft 16 mount-ed .iii the bearingsrll provided with tlirea-ded shanks openings in the blocks 19 so that the Shanks may move freely therethrough, there being.

providedV adjusting nuts 20 on the shanlrs .for moving the shaft 16 to adjust the tension .Secured to the -innersurfaces of the side boards ofgthe frame are bars '22, the saine being held. in spaced relation with the side boardsfto provide passageivays which `bars have converging ends 2,45 'defining a spout to direct the articles to the discharge Vendofthe machine.

As shown, more clearly by `Figure 2 of the` drawings, theside boardsarecut away providing discharge openingsand26 respectively onl opposite sides ofthe machine, ywhich discharge openings alloivA articles to pass laterally from the `machineinto s aclrs supported bythe adjustable saclrholders 27 Which are in the form of substantially .U- shaped members having their ends movable 18` which `threaded shanlsiopcrate through enlarged in the pipes QS'tliat inl turn have their ends extended beyond the side boards of the machine, the pipes being arranged in spaced relationvvith each other.

In order that the articles may be .directed to the, discharge openings, curved' members 29 are provided adjacent to the discharge openings, the curved members having con nection With `the bars 22 and with the inner surfaces `of the side boards of the machine. Thus it will be seen that as the endless conveyor is moving through the machine, artiica cles will be carried to the discharge openings.

The legs 6 at the discharge end of the machine are connected by means of the end bars 30, which bars support the adjustable sack carrier forming an important feature of the invention.

The sack carrier is indicated bythe reference character 3l and includes a main pipe 32 and lateral pipes 33 in which the substantially U-shaped members 34 are adjustably., held, there being provided prongs 35 for piercing the sack which is held thereby to prevent the sack from slipping from the sack holders.

Connected with the pipe 32 are vertical members 36 disposed at the ends of the pipe 32, the lower ends of the members 36 being connected with the platform 37.

The sack carrier also embodies a bar 38 disposed adjacent to the upper end thereof to which, bars 39 are pivotally connected,

-the bars 39 being also pivotally connected with the bars 40 at the lower ends thereof, the bars 40 having pivotal connection with the lower bar 30 as clearly shown by Figure 2.

Connecting the bars 39 andthe bar 30 are substantiallyv short arms 41, which arms 41 and bars 40 permit of swinging movement of the sack carrier transversely of the machine, to the end that one of the sack holders supporte-d at the upper end of the sack carrier may be brought to a position opposite the discharge spout of the machine.

Thus it will be seen that due to this construction a sack may be held in position to In the operation of the machine, the vegetables or fruit are positioned on the forward end of the machine and the crank handle 14 the central portion of the machine will of course pass to the discharge end of the machine where they will fall into the sacks supported at the discharge end.

I claim:

1. In combination with the horizontal spaced end bars of a supporting structure, a frame including an upper bar and side bars, connecting bars having pivotal connection with the upper bar of the frame, bars pivotally connected with the lower bar of the supporting structure and having pivotal connection with the connecting bars, bars connected with the connecting bars and having pivotal connection with one of the horizontal spaced bars of the supporting structure, and a platform at the base of the frame for supporting articles.

In combination with the horizontal spaced end bars of a supporting structure, a laterally swinging frame including an upper bar, a lower bar and side bars, bars connected with the upper bar of the frame, substantially short bars pivotally connected with the last mentioned bars and having pivotal connection with one of the horizontal spaced end bars of the supporting structure, and bars pivotally connected with one of the horizontal bars and having pivotal connection with the first mentioned pivotcd bars, and a platform forming a. part of the frame.

In testimony that I claim the foregoing as my own, l have hereto ailixed my signature.
